20130306592 | PLASTIC CAPACITIVE TOUCH SCREEN AND METHOD OF MANUFACTURING SAME - A method of removing portions of a conductive layer comprising a transparent conductive material and/or a metallic material disposed on a plastic substrate used for capacitive touchscreen devices includes providing a plastic substrate having a conductive layer disposed on a surface thereof and removing portions of the conductive layer at the surface of the plastic substrate to establish a pattern of electrically isolated conductive portions on the surface of the plastic substrate. The conductive portions or traces are electrically connected to a touchscreen controller, which is operable to determine a location of a touch or proximity of an object at or near the surface of the plastic substrate responsive to a detected change in capacitance. The removal process may comprise etching or laser ablating portions of the conductive layer at the surface of the plastic substrate. | 11-21-2013 |

20110246390 | SYSTEM AND METHOD FOR CONSTRUCTING INVESTMENT INSTRUMENTS, PORTFOLIOS , AND BENCHMARK INDEXES WITH ACTIVE LEVERAGED WRITTEN CALL OR PUT OPTIONS OVERLAY - An electronic pricing and trading system and method can be used for providing financial investment instrument or performance benchmark through an investment portfolio. The investment portfolio can have a long exposure to one or more underlying equities or an equity index. A technical rule can be used to determine a pricing trend associated with the underlying equities periodically. The technical rule can be electronically calculated based on prices of the one or more underlying equities or equity index investment, and a determined pricing trend is one of an up trend and a down trend. An option overlay component can be associated with the investment portfolio based on a determined pricing trend. For an up trend, the option overlay component contains written or shorting put options associated with the underlying equities or equity index. And, for a down trend, the option overlay component contains written or shorting call options associated with the underlying equities or equity index. | 10-06-2011 |

20140190950 | WELD COMPENSATION DEVICE - The present disclosure is directed to devices and methods for automating weld termination. In one embodiment, a compensation device is provided to grip a weld dam comprised of silicon dioxide. The compensation device is used to impart linear motion along an x-axis, y-axis, and z-axis, and rotational motion about the z-axis, to the weld dam. Via the imparted linear and rotational motion, the weld dam is then abutted against a surface of a workpiece, the workpiece comprising a first and a second section. In some embodiments, the workpiece surface includes uneven terminal ends of the first and second sections. In other embodiments, the workpiece surface is a bottom surface. | 07-10-2014 |
20140190951 | WELD DAMMING AND BACKING - The present disclosure is directed to methods for damming and backing welds. In one embodiment, a method of welding a workpiece is provided in which the workpiece includes a first section, a second section, and a weld groove disposed therebetween. Opposing edges of the first and second sections are positioned adjacent to each other and at least partially form a bottom of the weld groove. A silicon dioxide weld dam is abutted against a terminal end of the workpiece relative to a weld direction. The weld dam is positioned at a weld joint termination point to prevent molten metal from flowing through a terminal end opening of the groove at the weld joint termination point. The first and second sections are welded together along opposing edges in the weld direction up to the weld joint termination point. Finally, the dam is removed, exposing the terminal end of the workpiece. | 07-10-2014 |

20090089783 | PARTIAL ORDER REDUCTION USING GUARDED INDEPENDENCE RELATIONS - A system and method for conducting symbolic partial order reduction for concurrent systems includes determining a guarded independence relation which includes transitions from different threads that are independent for a set of states, when a condition or predicate holds. Partial order reduction is performed using the guarded independence relation to permit automatic pruning of redundant thread interleavings when the guarded independence condition holds. | 04-02-2009 |
20130283101 | Trace-Driven Verification of Multithreaded Programs Using SMT-Based Analysis - The method of testing for presence of a bug a multithreaded computer program under verification combines the efficiency of testing with the reasoning power of satisfiability modulo theory (SMT) solvers for the verification of multithreaded programs under a user specified test vector. The method performs dynamic executions to obtain both under- and over-approximations of the program, represented as quantifier-free first order logic formulas. The formulas are then analyzed by an SMT solver which implicitly considers all possible thread interleavings. The symbolic analysis may return the following results: (1) it reports a real bug, (2) it proves that the program has no bug under the given input, or (3) it remains inconclusive because the analysis is based on abstractions. In the last case, a refinement procedure is presented that uses symbolic analysis to guide further executions. | 10-24-2013 |
